ELECTRIC PLUG.

Specification of Letters Patent.

Patented Ang. 8, 1916.

Application filed December 26, 1914. Serial No. 879,132.

To all lwhom it 'may concern it known that l, Gnomi: ll. lneiiiini', aicitizen ot the United States. und n resident of Indianapolis, county ot'Marion, and Stute of Indiana, have invented u Certain new und usefullilleetrie Vlug; und Ido hereby dechire that the following; is ufull,clear, and exact description thereof, refer ence being haul to theaccompanying drawings, in which like letters refer to like parts.

The object ot this invention the iniproi'einent ot electrical plnifs for.mailling connections und disronneetions, in residein-.esl undelsewhere. lleretoiore, such plugs have been soldered und inode of onepiece :und ndnpted to screw into the Sori-:ets :and it trikes time tosrreu' the plug 'fullyr into the socket. und disconnect the suine und itrequires n turning movement of the plug which often interl'eijeil withby the elec trie lines or cords and often injures the lines :ind cords.

The chiel 'feature ot this invention eonsisis in milking snrh u. plug sothat it esili be slipped longitiidinullir into :i threaded socket und sothat it may be put in place instuntly und instantly removed withoutsubjeeting the `cord or line to :my twisting movement. 'Y

The full nature of the invention will he understood from the:ireoinpfinylug drawund the followingl de 'iptio und elninis:

ln the drzmi'ings, Figure 1 is u. dinul central seetionof the ping in e.sorlcet und the sorketba-ing parti il longitu4 place in i ly in seel"ig. 2 i

position for rei'novul. iif the line B-fl Fig: l. la on the line 1144 ofFig. 1.

'lhere is shown herein u lmnp socket 1() of ordinary type haring uninternally threaded sleeve 1l which is. inode of metal and eonngi-on 13,ns .shown in Figs. 1 -ind 3. The handle member lil hns a centrallongitudinal i'ereihly Circular in which .a the lines 17 and 13' are nsection located. The line 17 is connected withV .1 binding post 1l) 1nthe end 200i' the member 13, which end is formed of hard rubber or otherinsulating material. The'binding post 19 is secured to a terminal '21adapted to enplugY is inserted. The other line 18 is Connected with i1binding post 22 in the hard rubber portion 2O of the plug and is e011-neeted with :i metal threaded plate or cover 23 whirh surrounds theouter periphery of the hard rubber part Q0, :is seen in'Fig. 4. As shownin Fig. 3, the hard rubber. end of the stutionury member 13- isslightlyv more than seini-eirculiu and, therefore, the thi-ended plate.23 is slightly more than semi circular und its threads correspond withthe threads ot the sleeve 11 in the socket. the outer end of ineinber`13the usual slip connection is provided.

The member 14 is less than semi-circular and has :i pair of arms 26extending into the. recesses 15 of the member 13. vThese :ri-ms, asshown in Fig. 3, are curved in opposite directions so as to be slidablein said recesses. Therefore, the member 14 is slideble 'with referencet0 the member 13. The member 14 has a tapering.Y hard rubber end member9.8 adapted to wedge into the socket (it) gage the terminal 12 in thesocket when the tion 20 el theother member of the plug` and. hold theletter in conne-ation with the threaded sleeve 11, :is shown in Fig. 1.This will inuke us permanent connection between the plut,` und socket:is is provided with 'the' ordinary screw plug.

To remore the plug` 'from the socket, the member 14 is slipped from theposition, i th rele-.renee to the member 13, shown in 1, to that shownin Fig. 2f, so that its inner end isA outside or disenguges the socket.Then the inner end of the member 13 can be inoved laiternlly enough todisengage` the threads of the plates 1l find Q3 andv it een be thenwithdrawn from the socket. in order to enable this to be done, the innerend of the member l?, should not he niueh more than senii-eiri-le. 'Ibisensibles the plug to be witheiziiin from the socket without turningy it.liilrewisothe plug; con be inserteduin the. soc-.iet without turning it.This is done by holding` the two members 13 und lflin the position shownin Fig. 2, and inserLng; the endet n'ienibor 13 into they socket so thatthe threads of the plates 11 and E3-will engage each other. Then theinner end of the plug 13 is shoved up in the socket so as to wedge theplug in the socket. The dev ice is easily operated by one hand, the handholding the member 13 sta 4tionary while with .the thumb the member 13is moved ne way or the other to engageor disengage the socket, asdesired. The invention is shown herein long enough to befmanipulatedwith ones hand, but itis `it limited to a plug of anyv particular#length or size.

. Theinvention claimed is:

1. An electricplug adapted to engage a; socket, said plug' having Aaplurality o members, one' of said members having" a`n` innerlongitudinal groove, and guiding-and holding means extending from theother member into said groove, whereby the' two members may belongitudinally moved independently of each other, the end of. thegrooved member being formed to engage the inner wall of the socket andthe end of the other member being smooth and wedge shape longitudinalgroove, guiding and holding means extending from the other member/,1

into said groove, whereby the two members may be longitudinally movedindependently of each other, the end of the grooved member being formedto engage the inner wall of the socket'and .the end of the other memberbeing smooth and'wedge shape for wedg! ing between the end of saidgrooved member` and the wall of the socket, and electricaleers locatedin gro0ved-member.

Ih witness whereof, I have hereunto alf the 'groove of said Yfixed mysignature in the presence of the witnesses herein named.
